Division BAT 4 In order to prevent or, where that is not practicable, to reduce noise and vibrations, BAT is to use one or a combination of the techniques given below.
United Kingdom
| Description | Applicability | |
|---|---|---|
| Techniques for the prevention of noise and vibrations | ||
| a | Strategic planning of the plant layout in order to accommodate the noisiest operations, e.g. so that on-site buildings act as insulation. | Generally applicable in new plants. The layout of a site may limit the applicability on existing plants |
| b | Applying a noise reduction programme which includes noise source mapping, determination of off-site receptors, modelling of noise propagation and evaluation of the most cost-effective measures and their implementation. | Generally applicable |
| c | Performing regular noise surveys with monitoring of noise levels outside the site boundaries. | |
| Techniques for reduction of noise and vibrations from point sources | ||
| d | Enclosing noisy equipment in housing or by encapsulation and by soundproofing buildings. | Generally applicable |
| e | Decoupling individual equipment to pre-empt and limit propagation of vibrations and resonance noise. | |
| f | Point source insulation using silencer, damping, attenuators on noise sources, e.g. fans, acoustic vents, mufflers, and acoustic enclosures of filters. | |
| g | Keeping gates and doors closed at all times when not in use. Minimising the fall height when unloading roundwood. | |
| Techniques for reduction of noise and vibrations at the site level | ||
| h | Reducing noise from traffic by limiting the speed of internal traffic and for trucks entering the site. | Generally applicable |
| i | Limiting outdoor activities during the night. | |
| j | Regular maintenance of all equipment. | |
| k | Using noise protection walls, natural barriers or embankments to screen noise sources. | |
